I have a 2016 C450 and have developed an intermittent suspension squeak on both sides of the front. It is very loud in the car when I go over uneven roads. It sounds like bushings and isn’t always there but has gotten worse. It seems to sound like it is at the top of the suspension as it comes from the dash area. I can’t figure out how to locate it to determine what I need to replace without an expensive trial and error parts replacement. Has anyone had this and successfully located and fixed it? Is there a way to isolate the location? Thanks in advance.

My W204 has a reoccurring squeak on the front passenger side suspension area. Noticed it for a few years now. Most noticeable at low speeds when driving thru a parkinglot. I recently just heard it again. So I jack the car up and remove the wheel, spray pb blaster silicone spray on all the control bar bushings, ball joint boots, sway bar bushing etc. I even reach in between the strut springs and lift the plastic bellows and squirt a little on the shaft. The noise goes away.
If i had to guess I think its my sway bar bushing since it is cracking. But the sway bar is still mounted solid so im not about to replace it.
Once time i was driving and heard a loud squeak and immediately thought the strut mount or bearing was bad but for some reason I reached over and opened and closed the glove box and it went away. The noise really did sound like it was outside of the car.
Try spraying things with silicone spray lubricant and see if theres any change.
Thanks. I’ll give that a try. I hadn’t thought of the sway bar. Mine is on both sides and sounds like it is at the top of the suspension, but that could be that it just translates up the stack. The other weird thing is some days it is worse and some days it isn’t there at all. I can’t correlate that to the temperature either.
The cause of noises can be tricky to track down. Last fall I was hearing a clunking noise on my passenger side when going over bumps with the drivers side front wheel. Jacked up the car and started grabbing things trying to rotate/twist/shake to reproduce the sound. Turned out to be the passenger sway bar link which I had replaced two years prior. Seems the movement of the drivers wheel going up and down transferred thru the sway bar as it should and the passenger link was worn.
I was looking thru W202 parts diagrams and looks like the sway bar bushings are replaceable, Lemforder brand only $3/each.
Also noticed the shims at the top of the springs. Wondering if they are similar to the rears on the w204 where they fit up inside what looks like upside down metal bowls, they can crack and may rub around .
